[0025] The technical solution of this utility model will be further clearly and completely described below with reference to the accompanying drawings and through embodiments. The described embodiments are only some embodiments of this utility model. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0026] like Figure 1-5 As shown, a dehumidifier includes an outer shell 1 with an internal cavity. The top of the outer shell 1 has an air outlet 11 connected to the cavity, and the back of the outer shell 1 has an air inlet 12 connected to the cavity. A condenser 2 is installed inside the cavity, its position corresponding to the air inlet 12. A fan 3 is installed on the front of the condenser 2. A main board 4 is also installed inside the cavity, and a display screen 41 is installed on the main board 4 to display various usage statuses of the product. A water collection tank 5 is detachably installed at the bottom of the cavity, with a water collection chamber inside the water collection tank 5 for collecting condensate. An opening 51 is installed at the top of the water collection tank 5, connected to the water collection chamber, and its position corresponds to the condenser 2. A water collection feedback device 6 is also installed inside the cavity. By replacing the compressor and heat exchanger of a traditional dehumidifier with a condenser 2, the noise during operation of the dehumidifier is reduced, and its size and weight are significantly reduced, making it easier for users to move. It can be used in various scenarios such as wardrobes, cabinets, bathrooms, and storage cabinets.

[0027] like Figure 1-5As shown, the condensation device 2 includes a semiconductor cooler 21. A strip-shaped heat dissipation grille 22 is installed on the front of the semiconductor cooler 21, and the fan 3 is located on the front of the strip-shaped heat dissipation grille 22. A condenser plate 23 is installed on the back of the semiconductor cooler 21, and the position of the condenser plate 23 corresponds to the air inlet 12. The semiconductor cooler 21 is a device that generates cooling by utilizing the thermoelectric effect of semiconductors. After being powered on, the front temperature rises and the back temperature drops. Since the condenser plate 23 is connected to the back of the semiconductor cooler 21 with a lower temperature, its temperature is lower. When the fan 3 rotates and drives the air flow, the air will enter the cavity inside the outer casing 1 through the air inlet 12. When the air comes into contact with the condenser plate 23, the water vapor in the air will be pre-cooled and condensed into liquid water. The liquid water droplets flow down the condenser plate 23 under the action of gravity and are finally collected in the water collection tank 5 at the bottom. The semiconductor cooler 21 is electrically connected to the motherboard 4.

[0028] The strip-shaped heat dissipation grille 22 and the condenser fins 23 are both made of metal materials with good thermal conductivity, such as aluminum and copper.

[0029] like Figure 3-5 As shown, a support 13 is installed inside the cavity, and the condenser 2 and fan 3 are both fixed on the support 13. Air vents 131 are provided on both the left and right sides of the support 13 for airflow passing through the condenser fins 23. The strip-shaped heat dissipation grille 22 is vertically oriented, its bottom abutting against the bottom surface of the support 13, and its top forming a grille opening 221. A heat dissipation vent 132 corresponding to the grille opening 221 is provided on the top of the support 13, and the top of the heat dissipation vent 132 corresponds to the air outlet 11. The airflow direction of the fan 3 is aligned with the strip-shaped heat dissipation grille 22. The main board 4 is installed inside the cavity on the front of the fan 3. When the fan 3 rotates... When the air flows, the air will pass through the air inlet 12, condenser 23, air guide 131, fan 3, strip heat dissipation grille 22, grille opening 221, heat dissipation vent 132, and air outlet 11 in sequence before being discharged. Since the motherboard 4 is located in the cavity in front of the fan 3, part of the airflow cooled by the condenser 23 will flow to the vicinity of the motherboard 4 to cool the motherboard 4, thereby improving the heat dissipation effect of the motherboard 4. The bottom of the bracket 13 is provided with a funnel-shaped water drain trough 133. The top of the funnel-shaped water drain trough 133 corresponds to the position of the condenser 23, and the bottom of it is provided with a drain outlet 1331. The bottom of the drain outlet 1331 corresponds to the position of the opening 51.

[0030] like Figure 3-5As shown, a water collection feedback device 6 is installed inside the cavity. The water collection feedback device 6 includes a limiting tube 61. The limiting tube 61 has a strip-shaped water inlet 611 that runs vertically through it, allowing water from the water collection tank 5 to flow into the limiting tube 61. The bottom of the limiting tube 61 passes through an opening 51 inside the water collection tank 5. A float 62 is installed inside the limiting tube 61 that can be raised and lowered. The highest position that the float 62 can rise to corresponds to the highest water level in the water collection tank 5. A touch switch 63 is installed at the top of the limiting tube 61. The touch switch 63 is electrically connected to the main board 4. When the water level in the water collection tank 5 reaches the highest position, the float 62 will rise to the highest position and trigger the touch switch 63. The touch switch 63 will send a command to the main board 4, which will then control the condenser 2 and the fan 3 to stop working to prevent excessive water from overflowing from the water collection tank 5.

[0031] The touch switch 63 can be a spring touch switch, which compresses the spring by floating the float 62 to connect the contacts, thereby closing the circuit; the touch switch 63 can be a resistive touch switch or a capacitive touch switch, and the float 62 is made of metal material; the touch switch 63 can also be a proximity switch.

[0032] like Figure 3-5 As shown, a top cover 52 is provided inside the opening 51 at the top of the water collection tank 5. A water collection trough 521 is provided on the top cover 52. A water collection port 5211 communicating with the water collection cavity is opened at the bottom of the water collection trough 521. The position of the top of the water collection trough 521 corresponds to the condenser fin 23. By providing the top cover 52, water can be prevented from splashing out of the water collection tank 5 during transportation. The top of the limiting tube 61 is fixed on the top cover 52, and the top of the touch switch 63 is fixed on the bracket 13.

[0033] like Figure 5 As shown, a temperature sensor 24 is also provided on the condenser plate 23. The temperature sensor 24 is used to detect the temperature of the condenser plate 23. The temperature sensor 24 is electrically connected to the motherboard 4. When the temperature of the condenser plate 23 is too low, in order to prevent frost from forming on its surface, the motherboard 4 will control the condenser device 2 and the fan 3 to stop working, so that it can naturally return to room temperature to achieve the defrosting effect. Alternatively, the motherboard 4 can control the semiconductor cooler 21 to connect to a reverse current, so that the side of the semiconductor cooler 21 connected to the condenser plate 23 heats up, thereby driving the temperature of the condenser plate 23 to rise to achieve the defrosting effect.

[0034] like Figure 2 and 5 As shown, a grille shell 111 is provided on the outside of the air outlet 11, and a mesh grille 121 is provided at the air inlet 12, which can prevent foreign objects from entering the cavity and make the dehumidifier look more beautiful.

[0035] like Figure 2As shown, the outer surface of the outer casing 1 is also provided with a handle 14 to facilitate the user's movement of the dehumidifier.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
